BEWARE of Hervey's Spax Shocks! Washers pulled through mounting...

Where did you find them on their website?
Is this the one: http://www.protechshocks.co.uk/
I just know about the protech because of Martin Gutoswski from England.
On the other hand, I don't think he sale them right now?

This is the web page I looked at: http://www.protechshocks.co.uk/build-a-shock

Design you own configuration using the base shock models. The ends are changeable to fit you needs.

For those that had the washers pull through, how did you originally tighten the first nut on top of the shock? Did you bottom it out at the end of threads like you are supposed to or just tighten it until the bushings started to compress? I'm wondering if they aren't tight enough it could cause play which would then allow a good jolt to pull them through??? I've had the Spax for nearly two years now and will inspect them soon to verify the washers still look good.

You should not bottom out the nut. Just tight enough so the bushing expands to the edge of or slightly bigger than the washer provided.
